【Abstract】 A variety of assumptions is often made for the derivation of vertical momentum equation in hydrodynamics in an attemp to simplify the computational procedures. Nevertheless, actual flows usually do not meet these requirements. Thus, numerical method based on the three complete momentum equations, so-called complete 3-D in contrast with quasi-3-D,is necessary in order to simulate even more complex phenomenon. The authors of this paper designed a computer code series by the "Index Replacing Rules" in complete 3-D calculation. Numerical results comparing with the k-ε turbulence model are very satisfactory for the Intake-under-Outlet cooling water flow in the static environment.更多还原
